Ihsan Taylor for shepherding the book; designer Aimee Harrison; and the several reviewers for the press. Two of these reviewers, who provided extensive comments, have made themselves known to me, and I gratefully thank them both: Greg Clancey, Professor of History, head of Tembusu College, and leader of the sts cluster at the National University of Singapore, has been my host and intellectual companion throughout my decade-plus engagements with Singapore -a consummate historian of science and technology in Asia and longtime engaged resident in Singapore; and Byron Good, Professor of Anthropology and Social Medicine at Harvard and Gadjah Mada University in Yogyakarta, who has been an intellectual companion since graduate school and with whom I co-teach and have learned to think especially about things psychological and affecting mental health, and who with Professor Mary-Jo DelVecchio Good has provided constant touch points for thinking about Indonesia, medical sociology, Turkey, Iran, and the Middle East. Quite apart from reading the manuscript, all three of them are constant internal audiences for what I write about this part of the world. They are, of course, not responsible for any remaining defects, and their rights to disagree are both inviolable and cannot shake deep friendship.
